Duration: 19:22

This video tests the terminal ballistics of bullets cast from J-B Weld epoxy across various calibers. While smaller pistol rounds like 9mm fragmented easily, larger calibers such as .45 ACP, .44 Magnum, and especially .50 BMG demonstrated significant penetration and damage. The .50 BMG round, weighing 262 grains, completely passed through the ballistic dummy, causing extensive bone damage. The conclusion is that J-B Weld bullets, despite their brittle nature, are surprisingly lethal, particularly in high-mass rifle calibers.

Quick Summary

J-B Weld bullets demonstrate surprising lethality, particularly in rifle calibers. While smaller pistol rounds may fragment, larger calibers like .50 BMG can pass completely through ballistic dummies, causing extensive bone damage. Rifle rounds like 5.56x45mm and .308 also showed good penetration.

Frequently Asked Questions

How do J-B Weld bullets perform in pistol calibers?

In pistol calibers, J-B Weld bullets show mixed results. A 24-grain 9mm round fragmented easily with shallow penetration. However, a 38-grain .45 ACP round performed better, breaking a rib and penetrating deeper while remaining mostly intact.

Are J-B Weld bullets lethal in rifle calibers?

Yes, J-B Weld bullets are surprisingly lethal in rifle calibers. A 5.56x45mm round stayed together and penetrated well, as did a .308 Winchester round. The massive 262-grain .50 BMG round passed completely through the dummy, causing extensive bone damage.

What was the performance of magnum revolver J-B Weld bullets?

Magnum revolver J-B Weld bullets caused significant damage but tended to fragment. A .44 Magnum round broke ribs but fragmented, and a .500 Magnum round shattered upon impact, creating multiple entry points but limited deep penetration due to fragmentation.

What is the main conclusion about J-B Weld bullets' lethality?

Despite their brittle nature, J-B Weld bullets are extremely lethal, especially when used in high-mass rifle calibers. Their performance varies significantly by caliber, with larger rounds demonstrating greater penetration and destructive power.
